On his website, Atchoum jokingly "writes" that some confuse him as an "owl, a mad scientist, a Gremlin, Lorax or the Grinch." But pictures of Atchoum have the Internet seriously frazzled: Is he a cat, or is he a dog?

ABC News reports that this whole cat/dog debate started when one man tweeted a picture of the pet. Since then, the picture has gone viral with many wondering exactly what animal Atchoum is.

If you guessed cat, you're right! Atchoum is a Persian cat, but because of a condition called hypertrichosis, he has extra-long hair.
